When assessing a client with a serum potassium level of 7.5 mEq/L (7.5 mmol/L), which intervention is most important for the nurse to implement?

Determine apical pulse rate and rhythm.

Observe color and amount of urine.

Compare muscle strength bilaterally.

Assess strength of deep tendon reflexes.

Answer and Explanation

The Correct Answer is A

Choice A reason: This is the most important intervention because a high serum potassium level can cause cardiac dysrhythmias, which can be life-threatening. The nurse should monitor the client's heart rate and rhythm closely and report any changes or abnormalities to the healthcare provider.

Choice B reason: This is not the most important intervention because the color and amount of urine are not directly related to the serum potassium level. The nurse should assess the client's renal function and fluid balance, but these are not the priority assessments.

Choice C reason: This is also not the most important intervention because the muscle strength is not the most sensitive indicator of the serum potassium level. The nurse should evaluate the client's neuromuscular status and watch for signs of weakness or paralysis, but these are not the priority assessments.

Choice D reason: This is another incorrect intervention because the deep tendon reflexes are not the most reliable indicator of the serum potassium level. The nurse should check the client's reflexes and note any hyperreflexia or hyporeflexia, but these are not the priority assessments.

Correct Answer is A

Explanation

Choice A reason: This is the correct action because the nurse should provide realistic expectations and positive reinforcement to the client. Lifestyle changes such as exercise can improve sleep quality and duration, but they may not have immediate effects. The nurse should encourage the client to continue the workout program and follow good sleep hygiene practices.

Choice B reason: This is not the best action because the nurse should focus on the client's sleep problem rather than the weight loss goal. While weight loss can be a benefit of exercise, it is not the primary reason why the client started the workout program. The nurse should not make the client feel that weight loss is the only measure of success.

Choice C reason: This is also not the best action because the nurse should not interrogate the client about the details of the exercise schedule. The nurse should respect the client's autonomy and preferences regarding physical activity. The nurse can offer suggestions or resources to help the client optimize the exercise schedule, but should not imply that the client is doing something wrong.

Choice D reason: This is another incorrect action because the nurse should not encourage the client to exercise every day or close to bedtime. Exercising too frequently or too late can interfere with the body's circadian rhythm and cause sleep problems. The nurse should advise the client to exercise at least three times a week and avoid exercising within three hours of bedtime.

A. Serum potassium and sodium levels B. Neutrophil count C. Blood pH level D. Hematocrit

Correct Answer is B

Explanation

Choice A reason: Serum potassium and sodium levels are not relevant to the assessment of the wound infection. They are electrolytes that regulate fluid balance, nerve conduction, and muscle contraction. They may be affected by dehydration, renal failure, or diuretics.

Choice B reason: Neutrophil count is the most relevant laboratory value to note before reporting the wound infection. Neutrophils are white blood cells that fight bacterial infections and inflammation. A high neutrophil count indicates an acute infection or inflammation, while a low neutrophil count indicates a compromised immune system or a chronic infection.

Choice C reason: Blood pH level is not relevant to the assessment of the wound infection. It is a measure of the acidity or alkalinity of the blood. It may be affected by respiratory or metabolic disorders, such as acidosis or alkalosis.

Choice D reason: Hematocrit is not relevant to the assessment of the wound infection. It is the percentage of red blood cells in the blood. It may be affected by anemia, dehydration, or polycythemia.
